Be it known that I, ARNoI'oMioHoUma v citizen of Switzerland', residing at Yverdon, Canton of Vaud, in the Confederation of 5 Switzerland, have invented/certainnew and useful Improvements yinv Devices. for yRe siliently Supporting "Target, Disks, and "the like, of which 4the followingis alspec'iiiiea;

tion. In the case 'of targets,withjanlautomatic indicator device, in whichV the bullet v on striking# the target closes an electric circuit which acts ori-the indicator 'device andlopeif? ates the same, the want has been naturally felt of a .certa-in..elasticityfofthe target or of its parts in the rearward direction, Targets are already knownfin which the single' on bolts .passf As however y. parts or sections are .mounted mg through rubber.. fsleeves..

provision has alsobeen Valready" `made for preventing thebolts. from yielding' in the'v lateral directions by means of a metal guidewhich tightly surroundedthem about the centre of their length,.the target'parts` could yield only in the rearwarddirection.

Practical experience `has however shown that targets mountedso as kto yield only in the' longitudinal directionl of the bolts, a constant source of costly repairs. The bolts, rivetxheads and. thelil'r e, by means of vwhich the target parts are held, bre ak very soon owing to their being mounted onlyfin a. partially elastic manner.

This invention relates to a method of re` siliently mounting targets with automatic indicator devices and like devices, which is characterized by the target disk or disk lsections or the like'arranged at al distance Jfrom their indirect supporting organs, resting onv Figs. 4 and 5 are respectively a were vatidnpand a-:sideelevation provided with "the .elastic supporting device. .5 5

This"method of supporting the target vdisk allows the latter'itoyield in the rear-rv Ward directionaswell as in, any lateral .di-
